I recommend NOT buying these if you pedal alot, it restricts leg movement, therefore not suitable for 4cross, CROSS COUNTRY, bmx, dirtjump
recommended for steep DH trail, where you rarely pedal and mostly pedal when standing

Very light and comfortable, but they started to slide down 5 minutes into a climb exposing the upper knee. Didn't stay put going down hill either. Used for one ride only and went back to my trustee Roach guards. Gaurds not useful for 4X either, same problem with pads sliding down as soon as you hit the first jump. Also, too much material used in their construction. the pad wraps around the entire calf. Material is vented, but the extra material seems to defeat the purpose. If you ride hard and fast then these pads aren't for you. Good if your style is more laid back,"sit down and enjoy the scenery" type.
